By default, the Spinning Tile (Enemy Sprite) enemy's e tile animation is set to 4-frame 4-direction. But this animation causes the enemy to glitch, so it should be set to use the 4-frame animation instead. Also, the o tile animation is set to 2-frame 4 direction, but there is no tile defined. So maybe the old enemy tile should be assigned to what the new enemy tile is set to, and the o tile animation should also be 4-frame, and the new enemy tile should have its width set to 4 and height set to 1.
